PROCESS 01E TREATING ANIMAL FATS.

It'c Drawing.

To all whom it may concern:

Be it known that I, SUSIE ZAHNER, a Swiss citizen, residing at Bates, county of Fremont, and State of Idaho, have invented certain new and useful Improvements in Processes of Treating Animal Fats, of which the following is a specification.

This invention relates to processes of treating animal fats.

y process has for its object the improvement of the flavor of lard texture of tallow and other animal fats.

Fats that have previously been rendered may be treated by my process, or, the fat may be first cut into small pieces, as usual in any ordinary or common process of rendering lard or tallow with my process.

In carrying out my 'rocess, when approximately one half of the fat has been rendered, that is, when melted out of the cracklings, and when at a temperature of substantially 212 Fahrenheit or lower, I add new, unskimmed milk thereto in the proportion of one quart of milk to ten pounds of fat. Preferably, though not necessarily, the milk is added to the entire mass of rendered fat and cracklings but as the main feature of the invention is the addition of the milk to the fat to be rendered, I do not limit myself to its addition tothe fat when the fat is in the same mass with the cracklings. Instead of adding milk asspecified, the process may be carried out at this point and in the manner specified by the addition of from one-sixteenth quart to one quart of cream to every ten pounds of fat,

or, enough milk to contain approximately from one-sixteenth quart to one quart of cream to every ten pounds of'fat. My process also contemplates, instead of the addition of ordinary milk or cream, the addition of butter-milk whether contained in butter or separately, in the proportion above specified. Whether milk, cream, or butter-milk be added, the temperature of the fat being rendered should be not higher than 212 Fahrenheit and may be lower: ,The milk, cream or buttermilk may be added to any par-tor the entire mass and may be poured in rapidly, slowly, all at once, sired manner.

carrying out my process there may be I Specification of Letters Patent.

and the flavor and preparatory to treating it fats, whether rendered or raw,

,cracklings thereof, then or in any de- Pa tented J an. 5, 1915.

added to the fat to be rendered any constituent, constituents or combination of constituents or parts of which milk is composed or consists while either the milk or the fat, or both, are, preferably,

212 Fahrenheit or less templates the use of any ingredient of which milk constitutes a part. The fine flavor and improved texture being largely due to the cream in the milk, the proportion of the milk will vary accordin to its richness in cream. After the addition of the milk, cream, butter-milk, etc., as above specified, the entire mass is gradually heated, being stirred briskly meanwhile, until the fat begins to smoke. Thereupon, the heating and stirring may be continued until the mixture assumes a color and flavor according to the and the process conat a temperature of gree of heat and the period of time for carrying out this part of the process. The mix= ture should then be strained or pressed. On cooling, the strained or pressed product assumes a pure white color and is as palatable and soft as the best rendered sweet butter.

The bad qualities of inferior or spoiled can be very materially, corrected by my process.

Havin thus described my invention, What I c aim as new and desire to secure by Letters Patent, is

1. The process of treating fatty substances containing cracklings, consisting in melting out a art of the fat from the cracklings thereof: then addin a milk bearing element to the fat to be ren ered, and final y straining or pressing the resultingproduct.

The process of treating fatty substances having cracklings, consisting in melting out approximately one-half of the fatfrom the adding a milk-bearmg element to the fat to be rendered in the proportion of one quart or less of the milkbearing element to ten pounds of fat, and finally draining or pressing the product.

In testimony whereof, I hereunto aflix my signature in presence of two witnesses.
